The present invention belongs to the field of flame arresters, and discloses a buffered wall flow multi-channels flame arrester. The flame arrester comprises a buffering and splitting cover and a Z-type wall flow multi-channels flame arresting core, wherein the buffering and splitting cover has a round-bottom plain-top cylindrical shape or hemispherical shape, with pinholes distributed in the cover surface, and channels are arranged inside the Z-type wall flow multi-channels flame arresting core. In every two adjacent channels, the inlet of one channel is blocked, and the outlet of the other channel is blocked, and in the height direction in the central cross section of the flame arresting core, pinholes are arranged in the wall surfaces between adjacent channels, and adjacent upper and lower channels constitute a fluid channel.

A valve includes a valve body forming a channel defining a fluid flow path extending from an inlet port to an outlet port of the valve body via a gallery disposed therebetween, an opening disposed in communication with the gallery, a valve assembly at least partially disposed through the opening and in the gallery, and a set pin having a central longitudinal axis. A valve disc of the valve assembly moves between a first position spaced from a valve seat of the valve body and a second position in contact with the valve seat. The set pin is coupled to and at least partly supported by the valve assembly to maintain the valve assembly in the first position. The fluid flow path allows a fluid to flow through the valve body in a first direction and a second direction opposite the first direction. The set pin is adapted to disengage a portion of the valve assembly when contacted by a fluid traversing the fluid flow path in the second direction, allowing the valve disc to move to the second position.

A vapor taker system, a vessel-based solution to accommodate vapor destruction during hydrocarbon loading and/or lightering, is disclosed. The vapor taker has vapor destruction equipment, support fuel, and accommodation for loading hose connections as necessary to comply with air emissions requirements for the destruction of volatile organic compounds. The vapor taker system can be modular or fully integrated into a marine vessel such as a ship, barge, tanker, and so forth.

An enclosure, vehicle, and method for containing an overheating device are provided. An enclosure includes a body and a door that form a volume. The body includes is connected to a Venturi tube that is in communication with a fluid flow path flowing across an opening at an opposite end. In the event an overheating device is placed in the enclosure, a pressure sensor measures a pressure in the volume and a controller opens a first valve in a flow path through the Venturi tube so that air is pumped from the volume via the Venturi effect. The first valve is closed when the measured pressure drops below a threshold pressure. The enclosure can also include an extinguishing agent that can be expelled into the volume if a temperature sensor measures a temperature above a threshold temperature.
